Arthur Nearly A Hurricane, Pressure Dropping

Wed, 07/02/2014 - 16:03

As expected, Arthur is strengthening and is very close to being a hurricane. The pressure reported by Air Force Recon is 992 millibars, down from 995mb 2 hours ago. It will likely become a hurricane tonight.

A hurricane warning has been issued for the North Carolina coast from Surf City to Duck, including the Pamlico and Albemarle Sounds.

Forecast track shifted just a little west. The intensity forecast is not really changed. But the global models think that the storm will increase in intensity significantly and in size of wind field. The westward shift and the increase in the wind field prompted the upgrade to hurricane warnings.

The storm continues to try to become more organized. You can see new thunderstorms building on the east side of the storm.

There are three reconnaissance planes in the storm right now sending back information on Arthur.

A Look at Alabama’s Weather This Afternoon

Wed, 07/02/2014 - 14:40

An interesting weather map this afternoon across the Southeast.

Click image to enlarge and explore.

On the visible satellite, you can clearly see tropical storm Arthur off the Northeast Coast of Florida, moving north northeast at 8 mph.

I overlaid the 500 mb height contours in green so that you can see a distinct upper level disturbance by the Mississippi River.

Radar shows intense storms along the Mississippi River north of Vicksburg. Severe thunderstorm warnings are in effect. The SPC has just issued a severe thunderstorm watch for much of Mississippi and Louisiana.

This activity will track eastward along a stalled frontal boundary that lies generally along I-59. You can see that in the top left panel. Temperatures are around 90F north ofthe front and in the middle 90s to the south.

The HRRR model indicates that the storms will weaken as they push into Alabama after 7 p.m. Here is the model reflectivity for 8 p.m.:

But they are dissipated a couple of hours later according to the model.

We will keep out eyes on them.

The New Potential Storm Surge Flooding Map

Wed, 07/02/2014 - 12:26

It is time to start learning about the new NWS Experimental Potential Storm Surge Flooding Map. The first ones were issued last evening by the National Hurricane Center for Arthur.

A few notes:

…The graphic shows a reasonable idea of worst-case scenario surge flooding from the storm. It is a map of the POTENTIAL flooding. It shows areas that COULD be affected by storm surge flooding, not necessarily how much water will be over each location in the shaded areas.

…There is a 10% exceedance factor, meaning that there is a 1 in 10 chance that the surge at any location could be higher.

…The flooding shows is only due to surge from the ocean, not rainfall flooding or flooding due to levee breaks or trapping.

…The product does take into account uncertainty in the track, size and intensity of the storm.

…Remember that weather conditions can change and so will this map.

…It is not a flood plain map. Storm surge can occur in areas that are NOT in a flood plain. Surge can occur miles inland.

…Evacuation zones may not correspond exactly with the surge flood map. People in evacuation aras should heed the advice of local emergency managers always.

…Remember that storm surge can occur well below and even after the center of the storm passes. In Ike on the Bolivar Peninsula, storm surge cut off evacuation routes nearly 36 hours before the arrival of the center.

…The product will be issued when hurricane or tropical storm watches are issued for any part of the Gulf or East Coasts of the United States.

Here is the current map from Advisory #7 at 10 a.m. this morning:

Zooming in on the Charleston SC area, a place that is very vulnerable to water inundation. The yellow shading indicates locations that could receive over 3 feet of flooding above ground, but less than 6 feet. The “above ground” indication is important since it takes into account land elevation. Keep in mind the 10% chance it could be

Take time to familiarize yourself with the product if you have interests along the Gulf of East Coast so that you will be ready to use it when a hurricane or tropical storm threatens.

Here is a short video on the product from the National Hurricane Center:

Notes on Arthur

Wed, 07/02/2014 - 10:22

I will keep some notes going today on here about Arthur, updating them at the top of the post until the next advisory comes out.

AT 10 AM CDT
———————————————–
LOCATION…29.1N 79.1W
ABOUT 105 MI…165 KM ENE OF CAPE CANAVERAL FLORIDA
ABOUT 260 MI…420 KM SSE OF CHARLESTON SOUTH CAROLINA
MAXIMUM SUSTAINED WINDS…60 MPH…95 KM/H
PRESENT MOVEMENT…N OR 360 DEGREES AT 7 MPH…11 KM/H
MINIMUM CENTRAL PRESSURE…997 MB…29.44 INCHES

Click image to enlarge

As you can see from the updated graphic, tropical storm warnings have now been issued for the entire North Carolina coast.

There is still a tropical storm watch for a portion of the South Carolina coast.

There is a hurricane watch for the Outer Banks.

There are numerous tropical storm warnings in effect for the coastal waters offshore.

The official forecast track has been nudged slightly east but brings the center within 50 miles of Cape Hatteras during the pre-dawn hours Friday.

The wind probabilities are about the same as late last night, except they have increased slightly on the Outer Banks for tropical storm force winds, around 75-80%.

SATELLITE
The storm ingested a little dry air last night and took a hit in appearance, but it appears to be moistening again this morning. Tropical cyclones are like little steam engines, puffing up and down as thunderstorms develop and mature. Arthur is starting to look stronger on satellite.

INTENSITY
Arthur is forecast to become a hurricane tomorrow and should peak at around 85 mph in intensity before it starts to weaken and lose tropical characteristics as it races northeast ahead of the approaching trough, moving over colder water.

RECON
No planes in the storm right now, but there are two low level missions that will reconnoiter the storm all day and night starting around noon. There are also three NOAA flights scheduled, including a high altitude flight for this evening.

Hot and Mostly Dry but Cooler Ahead

Wed, 07/02/2014 - 06:55

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

Tuesday was a warm day with a cumulus field and no activity on radar. Today with the approach of a weak frontal boundary, we might see the development of an isolated thunderstorm or two, but we’ve also seen some pretty significant warming to the lower atmosphere and I expect we remain mostly dry with one of the hottest days so far for 2014. With highs climbing into the middle 90s and some spots getting into the upper 90s, we will also see heat indices climb into the 100 to 105 range.

Additionally some dry air aloft around 700 millibars has increased the microburst potential for the area. If we see convection initiate, we will need to watch for storms to become briefly severe with damaging wind the big threat.

The surface high off to our northwest, the significant trough moving across the Ohio River Valley, and the development of Arthur off the East Coast of Florida will combine to bring some drier and cooler air into North and Central Alabama for July 4th!

Arthur has continued to improve in structure with an interesting view from the Melbourne, FL, radar. There has been some indication of a restructuring of the center which has taken the position of Arthur slightly east of the earlier location. Radar animation shows a rather slow northward travel to the center. Because of the restructuring to the storm, the forecast track has been adjusted slight east of the track we saw yesterday. Also tropical storm and hurricane watches have been issued for a large portion of the Carolina coastline.

The trough moving through the Ohio River Valley moves off the Mid-Atlantic coast on Friday and this will take Arthur out into the northern Atlantic after it moves very closely by the Outer Banks of North Carolina. The northwesterly flow aloft and the drier air coming from the north will bring us a great July 4th with high temperatures dropping back into the upper 80s.

Moisture will gradually increase over the weekend with upper level ridging over the southern tier of the US into the first of next week. This should bring us back to a more summer time type pattern with daily chances for showers and thunderstorms as highs climb back into the lower 90s.

Beach goers will see warm weather at the beach for the next several days with only isolated showers possible. Highs will be around 90 on the immediate coast and into the middle 90s inland. Sunshine should be in good supply with 7 to 9 hours of good sun.

Voodoo country was dominated by a huge upper high on the run yesterday. Today, just as we see fairly often, the pattern has changed with a deep trough along the eastern seaboard with the big ridge over the western states. This pattern, if it verifies, would keep the heat in check for the eastern US. Ah, but what will tomorrow bring?

Arthur He Does As He Pleases

Tue, 07/01/2014 - 22:08

The references to the Christopher Cross song from the movie Arthur are irresistible as we track our first tropical storm of the Atlantic season. Someone said today that it will only affect areas between the moon and New York City. Gotta love that one. My contribution is the title of this post.

First, let us reiterate that Arthur will have no direct impact on our weather in Alabama or the weather along the northern Gulf Coast. It will have a small, indirect hand in making the weather better through the Fourth of July weekend.

But, Arthur is a potential worst case scenario for forecasters and emergency managers. We have a relatively weak storm that has the potential to grow in to a significant hurricane pretty quickly while only a short distance from a coastline crowded with holiday vacationers.

Arthur will be strengthening more tomorrow while tracking more northeastward about 100 miles off the coast of northeastern Florida. It should become a hurricane tomorrow or tomorrow night.

By Thursday morning, the center should be about 125 miles southeast of Charleston, South Carolina and by nightfall, it should be about 80 miles southeast of Myrtle Beach.

The center may pass right over the Outer Banks of North Carolina early Friday morning as a strong Cat 1 hurricane with top winds of 85 mph.

Here is the NWS National Digital Forecast Database representation of the storm at 1 a.m. Friday morning, depicted in the wind field.

On the graphic, I have overlain the probabilities of tropical storm force winds (39 mph – blue), strong tropical storm force winds (58 mph – yellow) and hurricane force winds (74 mph – red) on the little colored number stacks. You can see about an even chance places like Charleston and Myrtle Beach will see tropical storm force winds and a better chance along the North Carolina coast.

Click image to enlarge

The best chance for hurricane force winds will be along the Outer Banks, but based on the official forecast, the probability for hurricane force winds there is still only about 20%. Hurricane force winds will be most likely along much of the Outer Banks early Friday morning, with improving conditions later in the day on the Fourth.

I have overlain the wind swatch along the official track as well, shown in blue, gray and red for TS, strong TS and hurricane force.

There is a tropical storm watch (shown in yellow) along the East Coast of Florida.

The impact to the South Carolina coast will not be tremendous, with a nearly even chance of tropical storm force winds. With the onshore flow ahead of the center, ides will be high, and there will almost certainly be flooding Charleston where it floods with any good inshore wind.

It is important to note that the forecast track can have errors. In fact, the “cone of uncertainty” from the NHC could carry the center as far west of Charleston SC or take it 150 miles east of Cape Hatteras. The good news is that the strongest wind field will be on the east, or oceanic, side of the storm.

The storm will quickly lose tropical characteristics as it races northeast, reaching Nova Scotia Saturday afternoon and Newfoundland Sunday evening.

If you are traveling to South Carolina or eastern North Carolina over the holiday weekend, check the latest forecasts and emergency information.

First Tropical Storm of the 2014 Season

Tue, 07/01/2014 - 10:20

The National Hurricane Center has upgraded Tropical Depression One to Tropical Storm Arthur. The complete text of the advisory is below.

Arthur is expected to move slowly northward along the East Coast of Florida for the next couple of days as seen in the track graphic and gradually gaining strength as it curves northeastward Thursday and Friday become a hurricane near the coast of North Carolina. Track guidance is looking good because of the strong similarity of the various models.

Arthur is not expected to have any direct impact on Alabama. Sinking motion on the western side of the storm will help to keep convection suppressed for the latter half of the week. Strong northerly flow aloft will bring some drier and slightly cooler air to our area for the Fourth of July.

Heat Goes Up

Tue, 07/01/2014 - 06:44

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

In a relatively complex pattern for the start of July, a frontal system will approach from the northwest at mid-week while Tropical Depression One, soon to be Arthur, slowly churns off the east coast of Florida. The front would hint at increased shower chances, but the presence of the tropical disturbance and the sinking motion associated with it will counter the actions of the front. The result is a decrease in precipitation chances. Temperatures go up temporarily with Wednesday likely to be one of the warmest days so far in 2014.

But the presence of the circulation off the Southeast US coast will help to bring in stronger northerly flow aloft and along with it some much drier air to go along with the overall sinking motion to the northwest of the tropical system. This means that most of us will see dry weather for the next several days.

The heat goes up with the temporary building of a ridge between the approaching front and the tropical system off the East Coast of Florida. The combination of surface high pressure to our northwest and the tropical system to the southeast will increase the northerly flow aloft and drive some drier air into the area. The net effect will be to drive temperatures back down for Thursday and Friday. The drier and slightly cooler air should provide us with a fabulous Fourth.

As we watch the future Arthur scoot along the Southeast US coast, the trough to the northwest will move to the Mid Atlantic Coast. This should take Arthur out into the North Atlantic while an elongated west to east ridge builds across the southern US. Moisture levels will gradually work their way back up bringing isolated showers back into the forecast for the latter part of the Fourth of July weekend and into the first of next week.

For Beach Goers, the week ahead along the Gulf Coast looks great. You can expect 8 to 10 hours of sunshine and only small chances for an isolated thunderstorm. There will be a slightly better chance Thursday, as the front approaches. Highs will be in the lower 90s right along the shore, with middle and upper 90s further inland. Lows will be in the upper 70s. Expect to see a refreshing sea breeze each afternoon as Gulf water temperatures are in the middle 80s.

Unfortunately the long range outlook looks pretty hot. The dreaded 594 heat bubble will raise it’s ugly head promising some pretty good heat for the middle of July for much of the eastern two thirds of the country.

One Is the Lonliest Number

Mon, 06/30/2014 - 22:23

Tropical Depression One has formed tonight east of Cape Canaveral.

It looks sad tonight on the NHC website. It doesn’t have a catchy name. It is simply called One.

FAST FACTS 10 PM CDT
———————————————–
LOCATION…27.6N 79.1W
ABOUT 105 MI…170 KM ESE OF CAPE CANAVERAL FLORIDA
ABOUT 210 MI…335 KM NNW OF THE NORTHWESTERN BAHAMAS
MAXIMUM SUSTAINED WINDS…35 MPH…55 KM/H
PRESENT MOVEMENT…SW OR 225 DEGREES AT 2 MPH…4 KM/H
MINIMUM CENTRAL PRESSURE…1009 MB…29.80 INCHES

The system will inch closer to the Florida coast overnight and turn west, then west northwest and then northwest and north tomorrow. It should become a tropical storm tomorrow. It will be named Arthur.

The system should begin to strengthen on Wednesday before turning northeast and it could be a strong tropical storm or even a minimal hurricane as it skirts the coast near Myrtle Beach, SC heading for a possible landfall along the Outer Banks of North Carolina. It will then head out to sea.

A tropical storm watch has been issued along the Florida East Coast from Fort Pierce to Flagler Beach.

Disturbance Triggering Storms over Northeast Alabama

Mon, 06/30/2014 - 13:39

Another disturbance was triggering showers and thunderstorms over Northeast Alabama this afternoon.

Some of these storms will be heavy with lots of lightning, heavy rain and gusty winds.

There could be an isolated instance of severe weather but it will not be widespread.

These showers and storms will thin this evening and maybe we can get to the advertised flat ridge of high pressure that is supposed to bring us drier conditions.

ARTHUR?
Our low pressure system east of the Florida East Coast continues to get better organized. The Hurricane Hunters are checking it out now and we will see if a tropical depression has already formed. The NHC has upgraded the 48 hour probability of that happening to 80%. The system will move to near the coast before turning north and northeast. It could affect the Carolinas on the third and Fourth.
